Calcium Carbonate (CaCO 3) is a precipitate of bicarbonate.Bicarbonate is the critical component in the measurement of temporary water hardness (carbonate hardness). This part of water hardness is defined via the titration of all carbonates, bicarbonates, and hydroxides and is expressed in equivalent amounts of calcium carbonate.
